For each dataset, the total number of mammograms (MMG) with the available breast density information are mapped to the corresponding BI-RADS categories. In CSAW, the breast percentage was obtained running LIBRA software. In OPTIMAM Hologic, the Volumetric Breast Density (VBD) percentage was obtained using Volpara software. In BCDR and INbreast, only the American College of Radiology (ACR) categories are available in the dataset information.
